You probably know this already but the thing about the fuel level sender is all about ground. That is what the variable resistor in the sender is doing...allowing either full ground or limiting the ground connection by increasing resistance. At empty, you'll have 0 ohms resistance in a perfect world. At full, you'll have 30 ohms resistance in a perfect world. Unfortunately none of the senders I've bought & tested sold by any of the usual suspects will test this way, although yours is close enough. The only sender I've found that will register the exact values is sold by a seller on eBay whose ID is renbusan. But you have either a ground problem or a sending unit problem, I think. Good luck.
